Hello Community!
Even though SimplePlanes 2 haven't been released yet, I'm ready to present you my collection of decals for it. You can download it here:
GOOGLE DRIVE LINK
It contains 3 folders:
1. Camouflages.

This folder contains different camo parts from the Su-37 "Terminator" and woodland camo parts. The "Terminator-..." pictures was manually circled by me in Photoshop from the Su-37 paint scheme. The woodland camo parts are separated parts from the automatically generated woodland camouflage in Substance Painter.
2. Decals.

This folder contains different roundels, flags, captions, downloaded from different places of Web and collected in this folder. It contains both real decals and decals from the Ace Combat and Project Wingman. You can see that all numbers and captions are white: it necessary so that you can choose any color in color picker for these captions.
3. Details.

This is the most "powerful" part of this texture pack and i'm proud to present it to you! It contains different shape hatches from F-16 and MiG-29. Also, it contains entire skins with rivets. I think it can help you to create realistic texture of fuselage and wings in SimplePlanes 2. Some pictures:

I have created all these detail textures myself during development of Textured Fuselage Block mod. And i really hope that this work have not been in vain and become handy tools for texturing in SimplePlanes 2.
